16 is the age of consent but they are still underage. Age of consent doesn't mean anything really, it doesn't protect you. The age gap is important. I don't you how old you are, but if those girls get mad at you for whatever reason and decide to accuse you of something you didn't do or their parents find out that they had sekc with an older man, trust me you're gonna be into serious trouble. You might end up in jail for a while. Tough decision I know but I would think about it twice. If you're barely 18 I think it's ok but if you're over 25... Be careful.
